Oct. 10/67, Dichogamy & Thyme-like Flowers

Bentham says flowers of two kinds, on same tree of Vine in S. of France (Planchon?) some which do not fully open & always set.—

Horwood & Smith of Kew says true with Hot-House plants — Horwood says shake vine & clouds of pollen fly about — Has never seen any insect visit flowers —

Flowers perfume house — can thus tell where is flower — (Cleistogene)

[Forms of flowers, p. 311: "or instance, Mr. Bentham informs me that in the South of France some of the flowers on the vine do not fully open and yet set fruit; and I hear from two experienced gardeners that this is the case with the vine in our hot-houses; but as the flowers do not appear to be completely closed it would be imprudent to consider them as cleistogamic."]
